My wife went to Uruope in 1983 to he your son with a new born. While she some coins. 1959to 1976 They have on the rev. 10 are these silver? what are worth?
It sounds like you have some 10 rappen coins. They are not silver, and they are not valuable. Even if uncirculated, a 1959-B or a 1960-B is only worth a few dollars. Circulated examples are very inexpensive.
